Signal to Noise Ratio (SNR) Measurement

Hi!
I would like to measure SNR of an acoustic signal where the frequency of the signal is 37.5 kHz. Theoretically, this can be done by performing FFT on a sampled data of the signal. My question can I directly pass the data into the Mojo board? Do I need an external ADC?

Thank you.

Interface Mojo and Arduino

Hi, I would like to interface Mojo FPGA and Arduino Mega. FPGA act as signal process board (audio) while Arduino serves board that carry sensors and actuators. The FPGA will process the audio signal and send the data to the Arduino Mega. How could I do this? Is it possible solution to create UART mo...
